MoMA Exclusive: An ancient timekeeper made modern. A smartly minimalist, black-and-white watch, the NU:RO consists of two dials that rotate to show the time inside the hourglass shape. While it looks complex, the time is simple to read: the hour appears in the top portion of the hourglass and minutes in the bottom. The NU:RO watch is sized to be wearable by men and women, and has a stainless steel case, a sapphire crystal face and a black leather wristband.
